To til It'll/07w it may concern:

Be it known that I, DANIEL D. Ntn zrenn, a

"the casing of the threshing-machine.

citizen of the United States, residing at Swan- 1 ton, in the county of Fulton and State of Ohio.

have invented a new and useful Grain-Sepal rator, of which the following is a specifica- 1 tion.

the 1st day of December, 1903.

The invention also consists in part in the novel construction and improved arrangement and combination of parts, which will be hereinafter fully described,and particularly pointed out in the claims.

illustrated a simple and preferred form of embodiment of the invention, it being, however,

understood that no limitation is necessarily made to the precise structural details therein i exhibited. but that the right is reserved to 3 any changes, alterations, and modificatitms to grate 4 is composed of a plurality of fishbacks 4", connected by rods 4", which are suitably spaced apart. so that separation of grain may take place freely at this point. .In the present instance the curved grate-bars are provided with laterally-extending prongs ortines 10 11), which are. curved in conformity with the en rvaturcofthe grate-bars and which extend laterally from the sides of the latter, being, however, sul'liciently spaced apart to provide the necessary clearance for the passage of the lingers 11 of the rotary beater 1.

12 and 13 represent, respectively, the'front and the rear straw rack or carrier, said racks being provided in the nsualmanner with hottoms composed of inclined slats 11, between 1 which grain may escape, and with fish-backs 1n the accompanying drawings has been which recourse may be had within the scope l of the invention and without departing from the spirit or sacrificing the efliciency of the same.

In said drawings, Figure 1 is alongitudinal vertical sectional view of a portion of a threshing-machlne constructed in accordance with the principles of the invention. detail top plan view of a portion of the separating-grate and related parts. perspective detail view of one of the bars of the scparating-grate detached. Fig. 1 is a detail plan view of the vibratory grate a.

Fig. 2 is a Fig. 3 is a Correspondingparts in the several figures i are indicated by like characters of reference throughout.

in the prior patent referred to above, a revoluble heater and picker 1 is provided, the same being located in rear of the usual threshing-cylinder 2 and concave 3, but separated from the latter by means of a vibratory grate i 15, serving to feed the straw in a re nwvard direction.

16 is a rock-shaft having arms 17 and 18 supporting. respectively; the rear end of the front straw-rack and the front end of the rear straw-rack. The frontend ofthe front strawrack 12 is supported by means of links, one of which is seen at 19.

20 is a rock-shaft having arms, as 21, supporting the rear end of the rear straw-rack 13 and also provided with arms 22, supporting the rear end of a fluted grail'i-board 23, the front end of which is supported by means of links, one of which is shown at 21.

Suitably supported by means of links 25, above the bottom of the threshing-machine casing, is a grain-pan 26, which receives the grain that is separated at the various stages of operation and which includes a sieve 27, through which the clean grain may pass to the point of discharge.

28 is a driven shaft having a pulley 29, which connected by a pitman 30 with an arm or crank extending from the rock-shaft 16. Another arm extending from said rockshaft is connected by a pitman 31 with the grain-pan 26, to which latter a reciprocatory movement will thus be imparted.

The vibratory grate 1 may be driven in any suitable manner, as by a link or pitinan 19, connecting with a supporting-link 19 of the rack 15, said link being obviously disposed exterior of the casing, which latter is provided with arcuate slots for the passage of the pivotal pins.

The revoluble picker and beater may be driven in any suitable manner and at any desired rate of speed, it beingunderstood, how- The cave passes over the vibratory grate L, which gives it an opportunity of loosening up and causes a considerable separation of grain to take place before the straw is engaged by the beater. The arms of the latter, which is operated at considerable speed, will engage the straw and toss it violently in a rearward direction onto the rack 12, causing the straw to be thoroughly disintegrated and the grain to be thoroughly separated therefrom. Owing to the peculiar construction of the grate-bars, movement of any portion of the straw in the direction of the cylinder is positively prevented, and what is of still greater importance the coaction of the beater-arms and the grate-bars provided with the prongs or tines 10 will tend to rend the straw asunder, thus insuring a thorough separation of the grain.

Having thus described the invention, what is claimed is 1. In a grain-separator, a separating-grate comprising a plurality of curved bars having laterally-extendingtines curved in conformity with the curvature of said bars.

2. In a grain-separator, a cylinder and concave, a stationary separating-grate curved re- Versely to the concave and spaced apart from the latter, and a grate supported for vibration between the concave and the stationary grate.

3. In a grain-separator, a cylinder and concave, a stationary separating-grate spaced from the concave and comprising a plurality of curved bars having prongs or tines, a picker and beater having radially-extending arms operating in the clearances between thetines, and a grate supported for vibration between the concave and the stationary grate.

4. In a grain-separator, a pair of strawracks, a link-supported grain-pan, a grainboard supported between the grairrpan and the rear strawrack, a rock-shaft having arms supporting the rear end of the front strawrack and the front end of the rear straw-rack, a rock-shaft having arms supporting the rear ends of the grain-board and the rear strawrack, links supporting the front ends of the grain-board and the front straw-rack, adriven shaft having a crank-wheel, a pitman connecting the latter wit-han arm extending from the rocksha'ft between the straw-racks, and a pitman connecting one of said straw-racks with the grain-pan.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
